covered with polyps, which are arranged alternately on the 

 branches. They are large and circular; the mouth is prominent; 

 the tentacles are short and thick — the two transverse ones lying 

 a little below the level of the others. The diameter of the largest 

 polyp is about 2 mm. The spines on the main stem are crowded, 

 and do not all point in one direction — an unusual feature. They 

 are arranged neither in rows nor in spirals. On the branches the 

 spines are short, sharp, and triangular. They are arranged in 

 longitudinal rows, seven of which can be counted from one aspect. 

 The members of a row are about one length apart.

The main stem is broken, and is only 5 cm. in length. It 

 gives rise to a branch which reaches the length of 8 cm., and is 

 then broken. It in turn gives rise to a branch 23 cm. in length. 

 The axis of this branch tapers very markedly, and gives off delicate 

 branches on all sides and in no definite order. These are mostly 

 directed upwards. The polyps, which are badly preserved, are 

 elongated in the direction of the longitudinal diameter of the axis, 

 and are twice as long as they are broad. They are about 1 mm. 

 in length. They lie close together, but are not crowded. The 

 tentacles are short. The spines are short, triangular, and com- 

 pressed, and are far apart. They are arranged in longitudinal 

 rows, six of which can be seen from one aspect.

A small delicate colony 5 cm. high. The stem is slender, and 

 gives off delicate branches irregularly at right angles to the stem. 

 Anastomoses occur, but are not frequent. The polyps are situated 

 on one side of the axis. They are small, and have short digiti- 

 form tentacles. The polyps are about 1 mm. apart. The spines 

 are sharp and triangular, and are arranged in irregular longitudinal 

 rows, six of which can be seen from one aspect. Members of a 

 row are about two lengths apart.
